The machine
Tunnel shot blasting machines are designed for blasting welded constructions, beams, and profiles of different shapes and dimensions. They are especially suitable for shot blasting work pieces of larger lengths. They can operate individually with their own rail or be integrated into an existing transport system. They can also integrate with paint application lines and drying chambers.
Work pieces are hung on hooks on the overhead transporter that transports work pieces through the tunnel part of the machine. On the lateral sides of the tunnel’s shotblasting part, turbines are carefully placed which provide the optimum coating and cleaning of a work piece, despite the fact that the work piece is not rotated in the shot blasting process under a jet of steel shot coming from the turbines. Work pieces pass on through the blow-off chamber in order for the shot blasting agent to be removed from exposed surfaces, finally exiting the machine.
Features
-Shot blast machines suitable for the treatment of products of middle/large sizes handled horizontally or of products middle/small dimensions hung to proper jigs.
-The handling of the work-pieces can be done by couple of hoists, overhead conveyor or driven trolleys at ground level.
-The blast operation is done in one pass on the whole component surface throughout the crossing of the tunnel.
-Downstream the blasting tunnel, it is possible to install manual blasting cabinet for re-touching or blowing /suction cabinet to remove possible residue shot on the work-pieces.
-Tunnel blast machines are very often installed in complete automatic lines of shot-blasting/painting systems.
